Volvo Tests 1.5 Hours Full Charge On-Board Charger

Widespread success for the electric car depends in huge part on reducing the charging time.

Volvo Car Corporation is testing a new fast-charger for electric cars that cuts recharging time to 1.5 hours.

Developed by Brusa, Volvo says the fast-charger operates six times faster than today’s on-board devices.

“We know that short recharging times and extensive operating range are a necessity for potential electric car consumers,” said Lennart Stegland, vice president Electric Propulsion Systems, Volvo Car Corporation. “The fast-charging unit helps cure what is known as ‘range anxiety’ since the car can be more easily recharged during the day. And even if you don’t have enough time for a 1.5-hour charge, plugging in for just 30 minutes will give you enough power for another 80 kilometers (49.70 miles) of driving,” Volvo declared the new charger will be installed and evaluated in a number of Volvo C30 Electric cars.”

The new 22-kw fast-charger is the world’s first charger that operates on a three-phase supply and is small enough to be fitted in an electric car.

According to Volvo, it offers the car owner two possibilities:

• Using a three-phase outlet with 32 amps gives an 80 km (49.70 miles) range in 30 minutes. A full charge takes 1.5 hours

• Plugging into an ordinary single-phase 230-volt European household outlet gives a charging time of 8-10 hours, depending on the available current

“The user can ‘top up’ the battery pack with electricity one or more times during the day. This means that the total daily range is significantly extended, yet with the same low operating cost compared to a car with a conventional power train,” said Stegland. “Giving customers more usable hours each day means that electric cars become more viable as a commercial proposition, in both the private and public sectors.”
